The existing divergencies in the development of forensic anthropology (FA) around the world justify an analysis of its situation in each country/region. Our objective is to report information gathered directly from professionals acting in the field of forensic anthropology in Brazil, with the aim of highlighting the challenges of the discipline and contributing to its advancement. The research consisted of personal visits in Medico‐Legal Institutes (IMLs) in nine states of the country and semi‐structured interviews with 16 professionals. Detailed analysis of the Results suggests the field of forensic anthropology, despite the engagement and dedication of its professionals, cannot yet be considered a well‐structured discipline across the country. The academic background of professionals is highly heterogenous. The applied methods vary, and common protocol is not always followed. The demand highly exceeds the available human resources. The lack of comparative material Results in high percentage of cases remaining unsolved. Important divergences exist in terms of infrastructure and professional resources between the states. The limited cooperation between different IMLs and between different sections of the same IML—together with a general disbelief in the usefulness of anthropological examination in forensic cases—hampers FA’s development. There is a great openness for scientific collaboration and an abundance of material for research. Our research demonstrated structural, political, and academic limitations that affect the FA field in Brazil. However, the expertise and dedication of professionals point to human potential as the chief strength of this discipline that supports and enables research, providing high‐quality services in a challenging context.  相似文献

The analysis of mitochondrial DNA (mtDNA) is a useful tool in forensic cases when sample contents too little or degraded nuclear DNA to genotype by autosomal short tandem repeat (STR) loci, but it is especially useful when the only forensic evidence is a hair shaft. Several authors have related differences in mtDNA from different tissues within the same individual, with high frequency of heteroplasmic variants in hair, as also in some other tissues. Is still a matter of debate how the differences influence the interpretation forensic protocols. One difference between two samples supposed to be originated from the same individual are related to an inconclusive result, but depending on the tissue and the position of the difference it should have a different interpretation, based on mutation-rate heterogeneity of mtDNA. In order to investigate it differences in the mtDNA control region from hair shafts and blood in our population, sequences from the hypervariable regions 1 and 2 (HV1 and HV2) from 100 Brazilian unrelated individuals were compared. The frequency of point heteroplasmy observed in hair was 10.5% by sequencing. Our study confirms the results related by other authors that concluded that small differences within tissues should be interpreted with caution especially when analyzing hair samples.  相似文献

Understanding the developmental precursors of juvenile violent sex offending can contribute to the promotion of effective early intervention and prevention programs for high-risk children and youth. However, there is currently a lack of research on the early characteristics of adolescents who commit violent sex offenses. Drawing on the literature regarding the generalist and specialist positions of criminal behavior, the aim of the present study was to compare childhood risk factors for three groups of juvenile offenders: (a) pure sex offenders (PSO; n = 28); (b) violent non-sex offenders (VNSO; n = 172); and (c) versatile violent sex offenders (VVSO; n = 24). Nineteen risk factors comprising four life domains (individual, family, peer, and school) were identified from a file review. Three hierarchical logistic regression analyses examined associations between risk factors and offender groups. The results reflected the underlying heterogeneity of the sample, offering support for both the specialist and generalist positions of criminal behavior. PSOs differed from VNSOs on the basis of higher odds for precocious sexual behavior. Second, VVSOs differed from VNSOs on the basis of higher odds for precocious sexual behavior, criminal family members, and an adolescent mother, as well as lower odds for poor school behavior. Third, PSOs were marginally more likely to have engaged in early overt antisocial behavior compared with VVSOs. Fourth, many of the childhood risk factors examined were not associated with any offender group. In conclusion, VVSOs appeared to differ on the greatest number of risk factors from VNSOs, suggesting that VVSOs share a more similar developmental pathway with PSOs. The prevention and future research implications of these findings are discussed.  相似文献

Posttraumatic stress disorder (PTSD) is common among maltreated youth but it remains unclear as to whether removal from home is as traumatizing as the maltreatment. This study examined 250 maltreated adolescents aged 11–17?years who were grouped on the basis of whether they (1) endorsed removal from home as their primary traumatic event, (2) endorsed removal from home as a secondary traumatic event, but not their primary traumatic event, or (3) did not endorse removal from home as traumatic. PTSD diagnoses as well as symptoms of PTSD, dissociation, depression, posttraumatic cognitions, and anger expression were measured. Adolescents who endorsed removal from home as their primary traumatic event reported significantly lower levels of PTSD and related symptoms than adolescents in the other groups. The findings are discussed within the context of transactions surrounding removal from home and support previous work that PTSD is a critical concern regarding many maltreated youth.  相似文献

Abstract

This article looks at Russia’s exercise of power politics in Ukraine and Syria as a way of improving its international status. Russia’s recent willingness to use power and coercion is theoretically counterintuitive as it appears to be in dissonance with the prevalent characterisation of the country as a status-overachieving inconsistent power. We argue that this behaviour is not the result of a consistent weighing of status against capabilities, but rather reflective of both internal and external dynamics. We analyse issues of identity, opportunity and costs as factors that influence Russian foreign action, showing that power politics will not solve Russia’s status-inconsistency problem in the long run.  相似文献

Technology transfer policies can bring public R&D to potential users, reduce burdens on public resources, and influence technology development. Patent licensing offers transparency, potentially higher research returns, and possible increased adoption of socially desirable technologies. However, it limits access to research results, and raises concerns that public institutions will alter their agendas. A review of the US Department of Agriculture's patent and licensing program addresses the types of technologies disseminated, social benefits associated with them, institutions licensing technologies, the importance of exclusivity, and whether research priorities have become oriented to private interests. Results suggest that USDA's patent licensing is not revenue driven, and its research agenda has not changed in response to the program. Licenses vary with respect to four important social benefits. Licensing program priorities are closer to those of the private sector than the USDA's research program. Partial or limited exclusivity may be sufficient to attract technology developers.  相似文献

In this article, we investigate factors affecting hate crime policies by examining anti-LGBT (lesbian, gay, bisexual, transgender) hate crime reports as a type of policy implementation. Analyzing state-level data drawn primarily from the US Census between 1995 and 2008, we examine how structural and social movement mobilization factors explain hate crime reporting. We find that anti-LGBT hate crimes are more likely to be reported in more urbanized states and in states with both split political elites and a greater number of LGBT social movement organizations. We discuss the implications of our findings for separating the drivers of policy passage from policy implementation and for complementary criminological and social movement explanations for hate crime reporting.  相似文献
